T-50 patent say inlet is usable to mach 3. F-22 and J-20 inlet is fixed not variable like in T-50.

A: 2010.
B: Those numbers has been repeated ad infinitum without any proof attached to them at all.
C: No reason to believe any of it, at all.

Pogo did say what range it will have on supercruise and max, but i can’t remember from top of my head. In other news, 710 has resumed flight…

EDIT; Actually it has been only taxiing so far. New engine? We shall see…

we kno T-50 will fly faster then F-22. T-50 has blended fuselage and much sleeker then F-22 and higher sweep angle. it have two peice canopy that take more heat so can go faster. look at both plains and you easily see T-50 is much thinner and lower drag.

Somehow I doubt they have info on the F-22 and J-20’s inlet performance, engine performance, material limits, exact airfoil specification, etc. It’s even more laughable in the case of the J-20 because Chengdu hasn’t even finalized the design, yet Zelin already proclaims higher max speed for the T-50? Give me a break.

I say Zelin’s claim is about as good as a USAF general calling the T-50 4.5 gen.

T-50 have a blended fuselage. While it have much bigger relative wing area it’s profile is reminescent of SR-71. it is much sleeker and bigger fineness ratio than F-22 and also have higher wing sweep.

Also T-50 have 2 piece canopy with frame and use silica glass that can withstand heat and stress better then F-22 one piece polycarb canopy. this also indicate higher speed of T-50. original speed requirement is mach 2.6 it was reduced slightly but still faster then F-22.

Those who rail on the T-50’s use of radar blockers conveniently forget that Boeing’s JSF submission would also have used blockers, not to mention that the EMD F-23 probably would’ve had them as well.

Of course, none of this means that s-ducts are obsolete, or vice versa. It all depends on the overall design. Obviously there’s more than one solution to a problem.

Try the head of the RuAF.

head of RUAF Alexander Zelin said T-50 has higher max speed and supercruise than F-22 and J-20. it will also have higher g load so more manuverable.

Victor Bondarev also say the T-50 is superior in most areas than F-22.

analysis here shows why the T-50 is a better aircraft than the raptor.

what is the goal ?

should be mach 1.9 – mach 2 supercruise.

Hollande maybe a cumquat, but you would be disappointed indeed if France was ran by the same gang that Russia is.

Can you be more specific about how Putin and the Kremlin are being “thieves”? While there may be some corruption in the Russian government, this is hardly unique to Russia and I don’t think it even approaches the US with their corporate “lobbying”. Lockmart is the perfect example of military industrial complex running out of control.

Something I noticed.

“…Так на испытаниях этой весной (2013 год) при полной загрузке топливом и массогабаритными макетами вооружений 4-й борт (054) взлетел с 310 метров, достиг крейсерской скорости 2135 км/ч и максимальной – 2610 км/ч, при этом был еще потенциал по разгону, а так же забрался на 24 300 метров – дальше не пустили”

“… So to test this spring (2013) with a full load of fuel and the weight and size mock-ups of arms 4th board (054) took off from the 310 meters, reached a cruising speed of 2135 km / h and the maximum – 2610 km / h, while the was more overclocking potential, as well as climbed to 24,300 meters – more is not allowed “

The given altitude reflects the goal of breaking an area of coverage of air defense Patriot PAC3 MIM-104F Flight altitude 79,500 feet (24,200 m).

It seems like there are serious holes in American warship defence ability.
